implement link history.</p>
<p>The QWebHistoryInterface is an interface that can be used to
keep track of visited links. It contains two pure virtual methods
that are called by the WebKit engine: <a href="qwebhistoryinterface.html#addHistoryEntry">addHistoryEntry</a>()
is used to add urls that have been visited to the interface, while
<a href="qwebhistoryinterface.html#historyContains">historyContains</a>()
is used to query whether the given url has been visited by the
user. By default the QWebHistoryInterface is not set, so WebKit
does not keep track of visited links.</p>
<p><b>Note:</b> The history tracked by QWebHistoryInterface is not
specific to an instance of <a href="qwebpage.html">QWebPage</a> but
applies to all pages.</p>
<hr /><h2>Method Documentation</h2><h3 class="fn"><a name="QWebHistoryInterface" />QWebHistoryInterface.__init__ (<i>self</i>, <a href="qobject.html">QObject</a>&#160;<i>parent</i>&#160;=&#160;None)</h3><p>The <i>parent</i> argument, if not None, causes <i>self</i> to be owned by Qt instead of PyQt.</p><p>Constructs a new <a href="qwebhistoryinterface.html">QWebHistoryInterface</a> with parent
<i>parent</i>.</p>


<h3 class="fn"><a name="addHistoryEntry" />QWebHistoryInterface.addHistoryEntry (<i>self</i>, QString&#160;<i>url</i>)</h3><p>This method is abstract and should be reimplemented in any sub-class.</p><p>Called by WebKit to add another <i>url</i> to the list of
visited pages.</p>


<h3 class="fn"><a name="defaultInterface" /><a href="qwebhistoryinterface.html">QWebHistoryInterface</a> QWebHistoryInterface.defaultInterface ()</h3><p>Returns the default interface that will be used by WebKit. If no
default interface has been set, WebKit will not keep track of
visited links and a null pointer will be returned.</p>
<p><b>See also</b> <a href="qwebhistoryinterface.html#setDefaultInterface">setDefaultInterface</a>().</p>


<h3 class="fn"><a name="historyContains" />bool QWebHistoryInterface.historyContains (<i>self</i>, QString&#160;<i>url</i>)</h3><p>This method is abstract and should be reimplemented in any sub-class.</p><p>Called by the WebKit engine to query whether a certain
<i>url</i> has been visited by the user already. Returns true if
the <i>url</i> is part of the history of visited links; otherwise
returns false.</p>


<h3 class="fn"><a name="setDefaultInterface" />QWebHistoryInterface.setDefaultInterface (<a href="qwebhistoryinterface.html">QWebHistoryInterface</a>&#160;<i>defaultInterface</i>)</h3><p>Sets a new default interface, <i>defaultInterface</i>, that will
be used by all of WebKit to keep track of visited links.</p>
<p>If an interface without a parent has already been set, the old
interface will be deleted. When the application exists <a href="qwebhistoryinterface.html">QWebHistoryInterface</a> will
automatically delete the <i>defaultInterface</i> if it does not
have a parent.</p>
